Invalid's bathtub seat

Abstract

Seat is journalled on an annular bearing, and is centrally apertured to permit cleansing of the invalid's personal parts. The seat is journalled, as aforesaid, on a track which is movable horizontally relative to a basic frame. Accordingly, the seat can be moved from an overhung disposition relative to an edge of a bathtub, to a centered disposition in the middle of the bathrub, and the seat can be turned from an outwardly-facing disposition thereof to a disposition turned ninety degrees therefrom. Limbs fixed to the frame support the frame within a bathrub, and an outwardly-extending arm is provided to engage an edge of the bathtub to insure against the apparatus tilting due to the weight of the invalid, especially when set upon the seat in the overhung disposition.

I claim: 
     
       1. An invalid's bathtub seat, comprising: a frame having (a) a platform, and (b) limbs, for supporting said platform within a bathtub, attached to said platform;   a seat, coupled to said platform, and journalled thereon for universal rotation;   said seat having a fully open central aperture; and wherein   said frame has a reciprocable track, to which said seat is coupled, and upon which said seat is rotatably journalled, as aforesaid;   said track comprising means for accommodating horizontal movement of said seat relative to said platform.   
     
     
       2. An invalid's bathtub seat, comprising: a frame having (a) a platform, and (b) limbs, for supporting said platform within a bathtub, attached to said platform;   a seat, coupled to said platform, and journalled thereon for universal rotation;   said seat having a central aperture; and wherein   said frame has a reciprocable track, to which said seat is coupled, and upon which said seat is rotatably journalled, as aforesaid;   said track comprising means for accommodating horizontal movement of said seat relative to said platform; and   said track has a plurality of rollers, rotatably mounted thereto, which engage said platform to effect the aforesaid horizontal movement of said track.   
     
     
       3. An invalid's bathtub seat, comprising: a frame having (a) a platform, and (b) limbs, for supporting said platform within a bathtub, attached to said platform;   a seat, coupled to said platform, and journalled thereon for universal rotation;   said seat having a central aperture; and wherein   said frame has a reciprocable track, to which said seat is coupled, and upon which said seat is rotatably journalled, as aforesaid;   said track comprising means for accommodating horizontal movement of said seat relative to said platform; and   said frame further has an arm, projecting outwardly therefrom, for engagement with an outer edge of a bathtub to stabilize said bathtub seat.   
     
     
       4. An invalid's bathtub seat, according to claim 1, further including: means coupled to said track for releasably locking said rotatably journalled seat in a selected rotation.   
     
     
       5. An invalid's bathtub seat, according to claim 1, further including: means coupled to said platform for releasably locking said seat in a selected, horizontally-moved disposition relative to said track.   
     
     
       6. An invalid's bathtub seat, comprising: a frame having (a) a platform, and (b) limbs, for supporting said platform within a bathtub, attached to said platform;   a seat, coupled to said platform, and journalled thereon for universal rotation;   said seat having a central aperture; and wherein   said frame has a reciprocable track, to which said seat is coupled, and upon which said seat is rotatably journalled, as aforesaid;   said track comprising means for accommodating horizontal movement of said seat relative to said platform; and further including   means coupled to said track for releasably locking said rotatably journalled seat in a selected rotation; and wherein   said locking means is resiliently biased in a locking disposition.   
     
     
       7. An invalid's bathtub seat, comprising: a frame having (a) a platform, and (b) limbs, for supporting said platform within a bathtub, attached to said platform;   a seat, coupled to said platform, and journalled thereon of universal rotation;   said seat having a central aperture; and wherein   said frame has a reciprocable track, to which said seat is coupled, and upon which said seat is rotatably journalled, as aforesaid;   said track comprising means for accommodating horizontal movement of said seat relative to said platform; and further including   means coupled to said platform for releasably locking said seat in a selected, horizontally-moved disposition relative to said track; and wherein   said locking means is resiliently biased in a locking disposition.
